Digital health care tech isn't just for hipsters. It's also for those young merely at heart. The Aging Technology Alliance formed a few years ago to help the elderly and their caregivers better take advantage of the latest health care tools.

Carmakers are also getting into the act. At last week's International Consumer Electronics Show, Ford showed off a prototype in-car health monitoring system. Ford's SYNC communications system will connect wirelessly to wearable Medtronic continuous glucose monitors. If the monitor senses a sugar level too high or low, it will inform the driver via SYNC's digitized voice.

Another idea is to connect drivers with allergies to Web sites like Pollen.com. So they can steer clear of areas with high pollen counts. Of course, the best thing drivers can do for their health is to watch the road.
